HISTORY
- In November 2006, Mullen Group companies Cora Lynn and Schmidt Drilling were combined to form Treo Drilling Services L.P. Treo took its first oil sands core sample shortly thereafter.
- Schmidt Drilling began operations in 1958 and was acquired by the Mullen Group in 2005. Schmidt Drilling started out drilling water wells and expanded its services to include wireline coring, shallow gas drilling and surface casing pre-sets.
- Cora Lynn was founded in 1980 and was acquired by the Mullen Group in 2003. Cora Lynn was a water well and coal exploration business through the 80s and early 90s before venturing into specialized core drilling and recovery for producers operating in Alberta's oil sands.
